1508.04429 | we explored a method to reconstruct the distribution function of the galactic thick disc within the action space where nearby thick - disc stars are distributed . by applying this method to 127 chemically - selected thick - disc stars in the solar neighbourhood , we found that the vertical velocity dispersion that corr... | 138 |
astro-ph0402505 | sma observations of the massive star - forming region iras18089 - 1732 in the 1 mm and 850@xmath0 m band reveal outflow and disk signatures in different molecular lines . the sio(54 ) data show a collimated outflow in the northern direction . in contrast , the hcooch@xmath1(2019 ) line , which traces high - density gas... | 209 |
1106.6018 | among its great findings , the iras mission showed the existence of an unidentified mid - ir feature around 21 @xmath0 m . since its discovery , this feature has been detected in all c - rich proto - pne of intermediate spectral type ( a g ) and - weakly - in a few pne and agb stars , but the nature of its carriers rem... | 230 |
